From NASA March 25, 2020 This photograph shows ripples in the surface of Denman Glacier in East Antarctica that throw shadows against the ice. The glacier is melting at a faster rate now than it was from 2003 to 2008 Credits: NASA Denman Glacier in East Antarctica retreated 3.4 miles (5.4 kilometers) from 1996 to…
Researchers show that high ancient shorelines do not necessarily reflect ice sheet collapse millions of years ago From the Canadian Institute for Advanced Research: For decades, scientists have used ancient shorelines to predict the stability of today’s largest ice sheets in Greenland and Antarctica. Markings of a high shoreline from three million years ago, for…
Recent snowfall anomalies in Dronning Maud Land, East Antarctica Enhanced snowfall on the East Antarctic ice sheet is projected to significantly mitigate 21st century global sea level rise. In recent years (2009 and 2011), regionally extreme snowfall anomalies in Dronning Maud Land, in the Atlantic sector of East Antarctica, have been observed. It has been…
From Rutgers University Global sea level likely to rise as much as 70 feet for future generations NEW BRUNSWICK, N.J. — Even if humankind manages to limit global warming to 2 degrees C (3.6 degrees F), as the Intergovernmental Panel on Climate Change recommends, future generations will have to deal with sea levels 12 to…
From the University of Texas at Austin New map reveals giant fjords beneath East Antarctic ice sheet Scientists from the U.S., U.K. and Australia have used ice-penetrating radar to create the first high- resolution topographic map of one of the last uncharted regions of Earth, the Aurora Subglacial Basin, an immense ice-buried lowland in East…
From AAAS online: Widespread Persistent Thickening of the East Antarctic Ice Sheet by Freezing from the Base Abstract An International Polar Year aerogeophysical investigation of the high interior of East Antarctica reveals widespread freeze-on that drives significant mass redistribution at the bottom of the ice sheet. While surface accumulation of snow remains the primary mechanism…
